I2C Gamma and VCOM Buffer with EEPROM

Applications Information

Power-Supply Decoupling

To achieve the best results when using the DS3510,

decouple all the power-supply pins (VCC and VDD) with a

0.01µF or 0.1µF capacitor. Use a high-quality ceramic

surface-mount capacitor if possible. Surface-mount com-

ponents minimize lead inductance, which improves per-

formance, and ceramic capacitors tend to have adequate

high-frequency response for decoupling applications.

SDA and SCL Pullup Resistors

SDA is an I/O with an open-collector output that

requires a pullup resistor to realize high-logic levels. A

master using either an open-collector output with a

pullup resistor or a push-pull output driver can be used

for SCL. Pullup resistor values should be chosen to

ensure that the rise and fall times listed in the I2C

Electrical Characteristics are within specification. A typ-

ical value for the pullup resistors is 4.7kΩ.
